THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL
STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT
WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT

OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not
installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to
comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital
devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television
communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its
peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Obtaining Technical Assistance
Technical Assistance Center
The Cisco TAC is available to all customers who need technical assistance with a Cisco product,
technology, or solution. Two types of support are available: the Cisco TAC website and the Cisco TAC
Escalation Center. The type of support that you choose depends on the priority of the problem and the
conditions stated in service contracts, when applicable.
We categorize Cisco TAC inquiries according to urgency:
•
Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities,
product installation, or basic product configuration. There is little or no impact to your business
operations.
•
Priority level 3 (P3)—Operational performance of the network is impaired, but most business
operations remain functional. You and Cisco are willing to commit resources during normal business
hours to restore service to satisfactory levels.
•
Priority level 2 (P2)—Operation of an existing network is severely degraded, or significant aspects
of your business operations are negatively impacted by inadequate performance of Cisco products.
You and Cisco will commit full-time resources during normal business hours to resolve the situation.
•
Priority level 1 (P1)—An existing network is “down,” or there is a critical impact to your business
operations. You and Cisco will commit all necessary resources around the clock to resolve the
situation.

Port Adapter Overview
The Cisco PA-8T-V.35, shown in Figure 1-1 on page 1-2, provides up to eight synchronous serial
interfaces for the chassis. The PA-8T-V.35 network interfaces provide a direct connection between the
high-speed bus in the router and external networks. Each PA-8T-V.35 interface provides full-duplex
(FDX) operation at T1 (1.544 Mbps) and E1 (2.048 Mbps) speeds. The V.35 interface is most commonly
used in the United States and throughout Europe.
All eight PA-8T-V.35 interfaces connect to external networks through a single port that has a 200-pin,
D-shell receptacle. You must use a V.35 compact serial cable to connect PA-8T-V.35 interfaces to an
external data service unit (DSU) or channel service unit (CSU). The compact serial cable attached to the
single receptacle determines the mode (DCE or DTE) for all eight interfaces.
Note
Although the Cisco 7304 PCI Port Adapter Carrier Card in the Cisco 7304 router, Catalyst RSM/VIP2,
the Catalyst 6000 family FlexWAN module, and the VIP support online insertion and removal (OIR),
individual port adapters do not. To replace port adapters, you must first remove the Cisco 7304 PCI Port
Adapter Carrier Card in the Cisco 7304 router, the Catalyst RSM/VIP2, the Catalyst 6000 family
FlexWAN module, or the VIP from the chassis, and then replace port adapters as required.
Cisco 7100 series, Cisco 7200 series, Cisco uBR7200 series, Cisco 7301 routers, and Cisco 7401ASR
routers support OIR of all port adapter types.

Figure 1-1
All PA-8T-V.35 serial interfaces support non return to zero (NRZ) and non return to zero inverted (NRZI)
format, and both 16-bit and 32-bit cyclic redundancy checks (CRCs). The default configuration is for
NRZ format and 16-bit CRC. You can change the default settings with software commands.
There is no default mode or clock rate set on the PA-8T-V.35 serial ports, although an internal clock
signal is present on all ports for data communications equipment (DCE) support. The internal clock
allows you to perform local loopback tests without having to terminate the port or connect a cable. To
use the port as a DCE interface, you must set the clock rate and connect a DCE compact serial cable. To
use the port as a DTE interface, you need only connect a data terminal equipment (DTE) compact serial
cable to the port. Because the serial adapter cables determine the mode and interface type, the
PA-8T-V.35 interface becomes a DTE when a DTE cable is connected to it.
If a DTE cable is connected to a port with a clock rate set, the DTE ignores the clock rate and uses the
external clock signal that is sent from the remote DCE. For a brief description of the clock rate
command, see the “Configuring Timing (Clock) Signals” section on page 5-10. For complete command
descriptions and instructions, refer to the publications listed in the “Related Documentation” section on
page iv.
Serial Interface Specifications
Serial signals can travel a limited distance at any given bit rate; generally, the slower the bit rate, the
greater the distance. All serial signals are subject to distance limits beyond which a signal degrades
significantly or is completely lost. Table 1-1 lists recommended transmission speeds and distances for
V.35 serial interfaces. The recommended maximum rate for V.35 is 2.048 Mbps.

OL-3563-03
Chapter 1
Overview
LEDs
Note
V.35 supports 2.048-Mbps rates without any problems; we do not recommend exceeding the above
specifications for transmission speed versus distance. Do so at your own risk. The total aggregate
bandwidth for the PA-8T-V.35 is 16 Mbps, which can be divided into 8 Mbps on two ports; 4 Mbps on
four ports; or 2 Mbps on eight ports.
LEDs
The PA-8T-V.35 has one row of eight status LEDs (one for each port) and one enabled (EN) LED. (See
Figure 1-2.) The green- and amber-colored LED for each port indicates port status.

After system initialization, the enabled LED goes on to indicate that the port adapter has been enabled
for operation.
The following conditions must be met before the PA-8T-V.35 is enabled:
•
Port adapter is correctly connected to the backplane or midplane and receiving power.
•
Valid system software image for the port adapter has been downloaded successfully.
•
System recognizes the port adapter or PA-8T-V.35-equipped VIP, Catalyst RSM/VIP2,
Catalyst 6000 family FlexWAN module, or Cisco 7304 PCI Port Adapter Carrier Card.
If any of the above conditions are not met, or if the initialization fails for other reasons, the enabled LED
does not go on.
Table 1-2 lists port LED colors and indications.

Port is initialized by the system (the software
recognizes the hardware), and a V.35 compact
serial cable is properly connected at the router
end and the network end.
Flashing Port is sending and receiving data in half-duplex
mode (Cisco 7200 series routers only).

One of these conditions applies:
•
Port is in loopback mode
•
Compact serial is not properly connected at
the router or network end
•
Hardware problem at the network end of the
compact serial cable
Port is administratively down.
Cables and Pinouts
The compact serial cable for the PA-8T-V.35 is available in DTE or DCE mode with a 200-pin, D-shell
receptacle at the router end and eight, 34-pin Winchester block-type receptacles or plugs at the network
end. (See Figure 1-3.) The compact serial cable for the PA-8T-V.35 is 6 feet (1.8 meters) long.
Note
The V.35 compact serial cable attached to the single PA-8T-V.35 port determines the mode (DTE or
DCE) of the eight PA-8T-V.35 interfaces.
Following are the product numbers, according to mode, for the PA-8T-V.35 compact serial cable:
•
DTE mode with a 34-pin, Winchester-type V.35 plug (CAB-OCT-V.35-MT[=])
•
DCE mode with a 34-pin, Winchester-type V.35 receptacle (CAB-OCT-V.35-FC[=])

Because the PA-8T-V.35 uses a special, high-density port that requires special compact serial interface
cables, we recommend that you obtain the cables from Cisco Systems. Figure 1-4 on page 1-5 shows the
connectors at the network end of the PA-8T-V.35 compact serial cable.

Overview
Port Adapter Slot Locations on the Supported Platforms
Catalyst RSM/VIP2 Slot Numbering
The Catalyst RSM/VIP2 can be installed in any slot except the top slots, which contain the supervisor
engine. The Catalyst RSM/VIP2 in a Catalyst 5000 family switch does not use interface processor slot
numbering; therefore, slots are not numbered in Figure 1-5. The PA-8T-V.35 can be installed into either
port adapter slot 0 or slot 1 on a Catalyst RSM/VIP2. Figure 1-5 shows a Catalyst RSM/VIP2 with two
port adapters installed.
Note
The Catalyst 5500 switch has 13 slots. Slot 1 is reserved for the supervisor engine. If a redundant
supervisor engine is used, it would go in slot 2; otherwise, slot 2 can be used for other modules. Slot 13
is a dedicated slot, reserved for the ATM switch processor (ASP) module. Refer to the Catalyst 5000
Series Route Switch Module Installation and Configuration Note for any additional slot restrictions for
the Catalyst RSM/VIP2.

Catalyst 6000 Family FlexWAN Module Slot Numbering
The Catalyst 6000 family FlexWAN module can be installed in any slot except slot 1, which is reserved
for the supervisor engine. The PA-8T-V.35 can be installed into either port adapter bay 0 or bay 1 on a
FlexWAN module. Figure 1-6 shows a FlexWAN module with two blank port adapters installed.
Note
Slot 1 is reserved for the supervisor engine. If a redundant supervisor engine is used, it would go in slot
2; otherwise, slot 2 can be used for other modules.

Identifying Interface Addresses
This section describes how to identify interface addresses for the PA-8T-V.35 in supported platforms.
Interface addresses specify the actual physical location of each interface on a router or switch.
Interfaces on the PA-8T-V.35 installed in a router maintain the same address regardless of whether other
port adapters are installed or removed. However, when you move a port adapter to a different slot, the
first number in the interface address changes to reflect the new port adapter slot number.
Interfaces on a PA-8T-V.35 installed in a Catalyst 6000 family FlexWAN module or a VIP maintain the
same address regardless of whether other interface processors are installed or removed. However, when
you move a Catalyst 6000 family FlexWAN module or a VIP to a different slot, the interface processor
slot number changes to reflect the new interface processor slot.
Note
Interface ports are numbered from left to right starting with 0.

three-part number in the format module-number/port-adapter-bay-number/interface-port-number.
See Table 1-5 on page 1-21 for the interface address format.
PA-8T-V.35 Synchronous Serial Port Adapter Installation and Configuration
1-22
OL-3563-03
Chapter 1
Overview
Identifying Interface Addresses
If the FlexWAN module is inserted in module slot 3, then the interface addresses of the PA-8T-V.35 are
3/0/0 through 3/0/7 (module slot 3, port adapter bay 0, and interfaces 0 through 7). If the port adapter
was in port adapter bay 1 on the FlexWAN module, these same interface addresses would be numbered
3/1/0 through 3/1/7.
Note
If you remove the FlexWAN module with the PA-8T-V.35 from module slot 3 and install it in module
slot 6, the interface addresses become 6/0/0 through 6/0/7.
Note
The FlexWAN module physical port address uses a zero- (0-) based port address, which differs from the
conventional Catalyst 6000 family one- (1-) based port address.
Cisco 7100 Series Routers Interface Addresses
This section describes how to identify the interface addresses used for the PA-8T-V.35 in Cisco 7100
series routers. The interface address is composed of a two-part number in the format
port-adapter-slot-number/interface-port-number. See Table 1-5 for the interface address format.
Cisco 7200 Series and Cisco uBR7200 Series Routers Interface Addresses
This section describes how to identify the interface addresses used for the PA-8T-V.35 in Cisco 7200
series routers or Cisco uBR7200 series routers. The interface address is composed of a two-part number
in the format port-adapter-slot-number/interface-port-number. See Table 1-5 for the interface address
format.
In Cisco 7200 series routers, port adapter slots are numbered from the lower left to the upper right,
beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202, slot 4
for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR. (Port
adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller—if present.)
The interface addresses of the interfaces on the PA-8T-V.35 in port adapter slot 1 are 1/0 through 1/7
(port adapter slot 1 and interfaces 0 through 7). If the PA-8T-V.35 was in port adapter slot 4, these same
interfaces would be numbered 4/0 through 4/7 (port adapter slot 4 and interfaces 0 through 7).
In Cisco uBR7200 series routers, port adapter slots are numbered slot 1 and slot 2 for the
Cisco uBR7246 and Cisco uBR7246VXR and slot 1 for the Cisco uBR7223. (Slot 0 is always reserved
for the Fast Ethernet port on the I/O controller—if present.) The individual interfaces always begin with
0. The number of additional interfaces depends on the number of interface ports on a port adapter.
The interface addresses of the interfaces on a PA-8T-V.35 in port adapter slot 2 are 2/0 and 2/1
(port adapter slot 2 and interfaces 0 and 1). If the PA-8T-V.35 was in port adapter slot 1, these same
interfaces would be numbered 1/0 and 1/1 (port adapter slot 1 and interfaces 0 and 1).
Cisco 7301 Router Interface Addresses
This section describes how to identify the interface addresses used for the Cisco PA-8T-V.35 port adapter
in Cisco 7301 router. The interface address is composed of a two-part number in the format
port-adapter-slot-number/interface-port-number. See Table 1-5 on page 1-21 for the interface address
format.

Identifying Interface Addresses
Cisco 7304 PCI Port Adapter Carrier Card Interface Addresses
This section describes how to identify the interface addresses used for the PA-8T-V.35 in the Cisco 7304
PCI Port Adapter Carrier Card in Cisco 7304 routers. The interface address is made of a two-part number
in the format port-adapter-slot-number/interface-port-number.
The Cisco 7304 PCI Port Adapter Carrier Card installs into Cisco 7304 router module slots 2 through 5
(See Figure 1-13.) The port-adapter-slot-number is the Cisco 7304 router module slot number. For
example, the interface address of port 0 on a PA-8T-V.35, in which the Cisco 7304 PCI Port Adapter
Carrier Card is installed in Cisco 7304 router module slot 3, would be numbered 3/0.
Cisco 7401ASR Router Interface Addresses
This section describes how to identify the interface addresses used for the PA-8T-V.35 in the
Cisco 7401ASR router. In the Cisco 7401ASR router, slot 1 is the port adapter slot you use for the
PA-8T-V.35. The interface address is composed of a two-part number in the format
port-adpater-slot-number/interface-port-number. See Table 1-5 on page 1-21 for the interface address
format.
VIP Interface Addresses
This section describes how to identify the interface addresses used for the PA-8T-V.35 on a VIP in
Cisco 7000 series and Cisco 7500 series routers.
Note
Although the processor slots in the 7-slot Cisco 7000 and Cisco 7507 and the 13-slot Cisco 7513 and
Cisco 7576 are vertically oriented and those in the 5-slot Cisco 7010 and Cisco 7505 are horizontally
oriented, all Cisco 7000 series and Cisco 7500 series routers use the same method for slot and port
numbering.
See Table 1-5 for the interface address format. The interface address is composed of a three-part number
in the format interface-processor-slot-number/port-adapter-slot-number/
interface-port-number.
If the VIP is inserted in interface processor slot 3, then the interface addresses of the PA-8T-V.35 are
3/1/0 through 3/1/7 (interface processor slot 3, port adapter slot 1, and interfaces 0 through 7). If the
port adapter was in port adapter slot 0 on the VIP, these same interface addresses would be numbered
3/0/0 through 3/0/7.
Note
If you remove the VIP with the PA-8T-V.35 (shown in Figure 1-16 on page 1-21) from interface
processor slot 3 and install it in interface processor slot 2, the interface addresses become 2/1/0 through
2/1/7.

Safety Guidelines
Electrical Equipment Guidelines
Follow these basic guidelines when working with any electrical equipment:
•
Before beginning any procedures requiring access to the chassis interior, locate the emergency
power-off switch for the room in which you are working.
•
Disconnect all power and external cables before moving a chassis; do not work alone when
potentially hazardous conditions exist.
•
Never assume that power has been disconnected from a circuit; always check.
•
Do not perform any action that creates a potential hazard to people or makes the equipment unsafe;
carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
Telephone Wiring Guidelines
Use the following guidelines when working with any equipment that is connected to telephone wiring or
to other network cabling:
•
Never install telephone wiring during a lightning storm.
•
Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
•
Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
•
Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. Port adapters and processor modules
comprise printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI)
shielding and connectors are integral components of the carrier. Although the metal carrier helps to
protect the board from ESD, use a preventive antistatic strap during handling.
Following are guidelines for preventing ESD damage:
Caution
•
Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
•
Connect the equipment end of the strap to an unfinished chassis surface.
•
When installing a component, use any available ejector levers or captive installation screws to
properly seat the bus connectors in the backplane or midplane. These devices prevent accidental
removal, provide proper grounding for the system, and help to ensure that bus connectors are
properly seated.
•
When removing a component, use any available ejector levers or captive installation screws to
release the bus connectors from the backplane or midplane.
•
Handle carriers by available handles or edges only; avoid touching the printed circuit boards or
connectors.
•
Place a removed board component-side-up on an antistatic surface or in a static shielding container.
If you plan to return the component to the factory, immediately place it in a static shielding
container.
•
Avoid contact between the printed circuit boards and clothing. The wrist strap only protects
components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
•
Never attempt to remove the printed circuit board from the metal carrier.
For safety, periodically check the resistance value of the antistatic strap. The measurement should be
between 1 and 10 megohms (Mohm).
FCC Class A Compliance
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference, in which case users will be
required to correct the interference at their own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference
stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment
causes interference to radio or television reception, try to correct the interference by using one or more
of the following measures:
•
Turn the television or radio antenna until the interference stops.
•
Move the equipment to one side or the other of the television or radio.
•
Move the equipment farther away from the television or radio.

Removing and Installing Port Adapters
This chapter describes how to remove the Cisco PA-8T-V.35 port adapter from supported platforms and
also how to install a new or replacement port adapter. This chapter contains the following sections:
•
Handling Port Adapters, page 3-1
•
Online Insertion and Removal, page 3-2
•
Warnings and Cautions, page 3-3
•
Port Adapter Removal and Installation, page 3-4
Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge
(ESD) damage.
Note
Caution
When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router or
switch to conform to electromagnetic interference (EMI) emissions requirements and to allow proper
airflow across the port adapters. If you plan to install a new port adapter in a slot that is not in use, you
must first remove the blank port adapter.
When powering off the router, wait a minimum of 30 seconds before powering it on again.
Handling Port Adapters
Caution
Always handle the port adapter by the carrier edges and handle; never touch the port adapter’s
components or connector pins. (See Figure 3-1 on page 3-2.)

Online Insertion and Removal
Several platforms support online insertion and removal (OIR) of port adapters; therefore, you do not
have to power down routers when removing and replacing a PA-8T-V.35 on Cisco 7100 series routers,
Cisco 7200 series routers, Cisco uBR7200 series, Cisco 7301 routers, or Cisco 7401ASR routers.
Although the Cisco 7304 PCI Port Adapter Carrier Card, the Catalyst RSM/VIP2, the Catalyst 6000
family FlexWAN module, and the VIP support online insertion and removal, individual port adapters do
not. To replace port adapters, you must first remove the Cisco 7304 PCI Port Adapter Carrier Card, VIP,
Catalyst RSM/VIP2, or Catalyst 6000 family FlexWAN module from the chassis and then install or
replace port adapters as required. If a blank port adapter is installed on the Cisco 7304 PCI Port Adapter
Carrier Card, the Catalyst RSM/VIP2, the Catalyst 6000 family FlexWAN module, or the VIP on which
you want to install a new port adapter, you must first remove the Cisco 7304 PCI Port Adapter Carrier
Card, the Catalyst RSM/VIP2, the Catalyst 6000 family FlexWAN module, or the VIP from the chassis
and then remove the blank port adapter.
Caution
To prevent system problems, do not remove port adapters from the Cisco 7304 PCI Port Adapter Carrier
Card, the Catalyst RSM/VIP2, the Catalyst 6000 family FlexWAN module, or the VIP, or attempt to
install other port adapters on the motherboard when the system is operating. To install or replace port
adapters, first remove the Cisco 7304 PCI Port Adapter Carrier Card, the Catalyst RSM/VIP2, the
Catalyst 6000 family FlexWAN module, or the VIP from its interface processor slot.
It is wise to gracefully shut down the system before removing a port adapter that has active traffic moving
through it. Removing a module while traffic is flowing through the ports can cause system disruption.
Once the module is inserted, the ports can be brought back up.
Note
As you disengage the module from the router or switch, online insertion and removal (OIR)
administratively shuts down all active interfaces in the module.
OIR allows you to install and replace modules while the router is operating; you do not need to notify
the software or shut down the system power, although you should not run traffic through the module you
are removing while it is being removed. OIR is a method that is seamless to end users on the network,
maintains all routing information, and preserves sessions.
The following is a functional description of OIR for background information only; for specific
procedures for installing and replacing a module in a supported platform, refer to the “Port Adapter
Removal and Installation” section on page 3-4.

OL-3563-03
Chapter 3
Removing and Installing Port Adapters
Warnings and Cautions
Each module has a bus connector that connects it to the router. The connector has a set of tiered pins in
three lengths that send specific signals to the system as they make contact with the module.
The system assesses the signals it receives and the order in which it receives them to determine if a
module is being removed from or introduced to the system. From these signals, the system determines
whether to reinitialize a new interface or to shut down a disconnected interface.
Specifically, when you insert a module, the longest pins make contact with the module first, and the
shortest pins make contact last. The system recognizes the signals and the sequence in which it receives
them.
When you remove or insert a module, the pins send signals to notify the system of changes. The router
then performs the following procedure:
Note
1.
Rapidly scans the system for configuration changes.
2.
Initializes newly inserted port adapters or administratively shuts down any vacant interfaces.
3.
Brings all previously configured interfaces on the module back to their previously installed state.
Any newly inserted interface is put in the administratively shutdown state, as if it was present (but
not configured) at boot time. If a similar module type is reinserted into a slot, its ports are configured
and brought online up to the port count of the originally installed module of that type.
Before you begin installation, read Chapter 2, “Preparing for Installation” for a list of parts and tools
required for installation.
Warnings and Cautions
Observe the following warnings and cautions when installing or removing port adapters.
Caution
Do not slide a port adapter all the way into the slot until you have connected all required cables. Trying
to do so will disrupt normal operation of the router or switch.
Note
If a port adapter lever or other retaining mechanism does not move to the locked position, the port
adapter is not completely seated in the midplane. Carefully pull the port adapter halfway out of the slot,
reinsert it, and move the port adapter lever to the locked position.
Caution
To prevent jamming the carrier between the upper and the lower edges of the port adapter slot, and to
ensure that the edge connector at the rear of the port adapter mates with the connection at the rear of the
port adapter slot, make certain that the carrier is positioned correctly, as shown in the cutaway in the
following illustrations.
Caution
When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the
card. Some platforms have an ESD connector for attaching the wrist strap.

You can install one single-width port adapter in a Cisco 7304 PCI Port Adapter Carrier Card. This
section provides step-by-step instructions for removing and installing a port adapter in a Cisco 7304 PCI
Port Adapter Carrier Card.
Warning
When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the
Cisco 7304 PCI Port Adapter Carrier Card. Some platforms have an ESD connector for attaching the wrist
strap. Do not directly touch the midplane or backplane with your hand or any metal tool, or you could
shock yourself.
To remove and install a port adapter in a Cisco 7304 PCI Port Adapter Carrier Card, refer to Figure 3-2
and do the following:
Step 1
If the Cisco 7304 PCI Port Adapter Carrier Card is still in the router, you must remove the Cisco 7304
PCI Port Adapter Carrier Card before removing a port adapter.
Step 2
To remove the port adapter from the Cisco 7304 PCI Port Adapter Carrier Card, turn the port adapter
lock from its locked and horizontal position shown in A of Figure 3-2 to its unlocked and vertical
position shown in B of Figure 3-2.
Step 3
Grasp the handle of the port adapter and pull the port adapter from the Cisco 7304 PCI Port Adapter
Carrier Card. (You have already disconnected the cables from the port adapter when removing the
Cisco 7304 PCI Port Adapter Carrier Card).

Attaching the PA-8T-V.35 Interface Cables
To continue your Cisco PA-8T-V.35 port adapter installation, you must install the port adapter cables.
The instructions that follow apply to all supported platforms. This chapter contains the following
sections:
•
Connecting a PA-8T-V.35 Compact Serial Cable, page 4-1
•
Determining the Port Mode, page 4-3
Connecting a PA-8T-V.35 Compact Serial Cable
On a single PA-8T-V.35, you can use only one compact serial cable. PA-8T-V.35 compact serial cables
are available only from Cisco Systems.
Caution
You can attach only an EIA/TIA-V.35 compact serial cable to the PA-8T-V.35 installed in your router.
Attaching a compact serial cable of another interface type to the port adapter could damage your router
or the hardware at the network end of the cable.
Use the following procedure to connect a compact serial cable to a PA-8T-V.35:
Step 1
Attach the compact serial cable directly to the receptacle on the PA-8T-V.35 and tighten the strain-relief
screws. (See Figure 4-1.)
Note
Port adapters have a handle attached, but this handle is not shown to allow a full detailed view
of each port adapter’s faceplate.
When attaching the cable receptacle on the PA-8T-V.35, use the cable-management bracket that
shipped with your router for extra strain relief.

Chapter 4
Attaching the PA-8T-V.35 Interface Cables
Determining the Port Mode
Determining the Port Mode
The compact serial cable connected to each port determines the mode of the ports (the electrical interface
type is always V.35). The default mode of the ports is data communications equipment (DCE), which
allows you to perform a loopback test on any port without having to attach a port adapter cable. For
information related to the loopback command, see the “Using the ping Command to Verify Network
Connectivity” section on page 5-29. Although DCE is the default, there is no default clock rate set on
the interfaces. On the Cisco 7100 series, Cisco 7200 series, Cisco uBR7200 series, Cisco 7301 routers,
or the Cisco 7401ASR router when there is no cable attached to a port, the software actually identifies
the port as cable type: None present rather than either a DTE or a DCE interface. On a Cisco 7304 PCI
Port Adapter Carrier Card, Catalyst RSM/VIP, Catalyst 6000 family FlexWAN module, and VIP, when
there is no cable attached to a port, the software actually identifies the port as Universal (cable
unattached) rather than either a DTE or a DCE interface.
Caution
You can attach only an EIA/TIA-V.35 compact serial cable to the PA-8T-V.35 installed in your router.
Attaching a compact serial cable of another interface type to the port adapter could damage your router
or the hardware at the network end of the cable.

To change the mode of a port online, use software commands to shut down the interface, replace the
compact serial cable, restart the interface, and (if necessary) reconfigure the port for the new interface.
At system startup or restart, the system polls the interfaces and determines the electrical interface type
of each port (according to the type of compact serial cable attached). However, the system does not
necessarily repoll an interface when you change the adapter cable online. To ensure that the system
recognizes the new interface type, shut down and reenable the interface after changing the cable.
If you are replacing a cable with a cable that has the same mode, these steps are not necessary (simply
replace the cable without interrupting operation).
Step 1
Enter configuration mode. At the privileged level of the EXEC, specify the port address and shut down
the interface. (See the “Using the EXEC Command Interpreter” section on page 5-1 for an explanation
of the privileged level of the EXEC.) Add additional configuration commands, if needed, before you exit
from configuration mode (before you press Ctrl-Z or enter end).
For a Cisco 7200 series, a Cisco 7100 series, a Cisco uBR7200 series, Cisco 7301 router, a
Cisco 7401ASR router, or a Catalyst RSM/VIP2, use the following example:
Router> enable
Password:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# interface serial 1/0
Router(config-if)# shutdown
Ctrl-Z
Router#
End with CNTL/Z.
For a VIP, use the following example:
Router> enable
Password:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# interface serial 3/1/0
Router(config-if)# shutdown
Ctrl-Z
Router#
End with CNTL/Z.
Step 2
Locate and remove the adapter cable to be replaced.
Step 3
Connect the new cable between the PA-8T-V.35 and the network connection. Tighten the thumbscrews
at both ends of the cable to secure it in the ports.
Step 4
Enter configuration mode again, bring the port back up, and save the running configuration to NVRAM.
For a Cisco 7100 series2, Cisco 7200 series, a Cisco uBR7200 series router, Cisco 7301 router, a
Cisco 7401ASR router, or a Catalyst RSM/VIP, use the following example:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# interface serial 1/0
End with CNTL/Z.

Chapter 4
Attaching the PA-8T-V.35 Interface Cables
Determining the Port Mode
Router(config-if)# no shutdown

Router#
Router# copy running-config startup-config
These steps prompt the system to poll the interface and recognize the new interface immediately.
When you configure a port for a DCE interface for the first time, or when you set up a loopback test, you
must set the clock rate for the port. When you connect a DCE cable to a port, the interface remains down
and does not function until you set a clock rate (regardless of the DCE mode default).
If you are changing the mode of the interface from DCE to DTE, you do not need to change the clock
rate for the port. After you replace the DCE cable with a DTE cable, and the system recognizes the
interface as a DTE, it uses the external clock signal from the remote DCE device and ignores the internal
clock signal that the DCE interface normally uses. Therefore, when you configure the clock rate on a
port for either a DCE interface or loopback, you can leave the clock rate configured and still use that port
as a DTE interface.
This completes the procedure for replacing a PA-8T-V.35 compact serial cable on the PA-8T-V.35.
Proceed to Chapter 5, “Configuring the PA-8T-V.35 Interfaces.”

Configuring the PA-8T-V.35 Interfaces
To continue your Cisco PA-8T-V.35 port adapter installation, you must configure the PA-8T-V.35
interfaces. The instructions that follow apply to all supported platforms. Minor differences between the
platforms are noted. This chapter contains the following sections:
•
Using the EXEC Command Interpreter, page 5-1
•
Configuring Half-Duplex and Binary Synchronous Communications, page 5-15
•
Checking the Configuration, page 5-17
Using the EXEC Command Interpreter
You modify the configuration of your router through the software command interpreter called the EXEC.
You must enter the privileged level of the EXEC command interpreter (also called enable mode) with
the enable command before you can use the configure command to configure a new interface or to
change the existing configuration of an interface. The system prompts you for a password if one has been
set.
The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>).
At the console terminal, use the following procedure to enter the privileged level:
Step 1
At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a
privileged-level password as follows:
Router> enable

Configuring the Interface
After you verify that the new PA-8T-V.35 is installed correctly (the enabled LED goes on), use the
privileged-level configure command to configure the new interfaces. Have the following information
available:
•
Protocols you plan to route on each new interface
•
IP addresses if you will configure the interfaces for IP routing
•
Bridging protocols you plan to use
•
Timing source for each new interface and clock speeds for external timing
If you installed a new PA-8T-V.35 or if you want to change the configuration of an existing interface,
you must enter configuration mode to configure the new interfaces. If you replaced a PA-8T-V.35 that
was previously configured, the system recognizes the new PA-8T-V.35 interfaces and brings each of
them up in their existing configuration.
For a summary of the configuration options available and instructions for configuring interfaces on a
PA-8T-V.35, refer to the publications listed in the “Related Documentation” section on page iv.
You execute configuration commands from the privileged level of the EXEC command interpreter, which
usually requires password access. Contact your system administrator, if necessary, to obtain password
access. (See the “Using the EXEC Command Interpreter” section on page 5-1 for an explanation of the
privileged level of the EXEC.)

Shutting Down an Interface
Before you remove an interface that you will not replace, replace a compact serial cable, or replace port
adapters, use the shutdown command to shut down (disable) the interfaces to prevent anomalies when
you reinstall the new or reconfigured interface processor. When you shut down an interface, it is
designated administratively down in the show command displays.
Follow these steps to shut down an interface:
Step 1
Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the “Using
the EXEC Command Interpreter” section on page 5-1 for instructions.)
Step 2
At the privileged-level prompt, enter configuration mode and specify that the console terminal is the
source of the configuration subcommands, as follows:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)#
Step 3
End with Crtl-Z.
Shut down interfaces by entering the interface serial subcommand (followed by the interface address of
the interface) and then enter the shutdown command. Table 5-1 shows the command syntax.

If you are configuring a DTE interface, proceed to Step 6. If you are configuring a DCE
interface, you need to configure the external clock signal, which is described in Step 5.
Set the clock rate with the clock rate command. (See the “Configuring Timing (Clock) Signals” section
on page 5-10.)
Router(config-if)# clock rate 64000

return to the EXEC command interpreter prompt.
Step 9
Write the new configuration to NVRAM as follows:
Router# copy running-config startup-config

This completes the procedure for creating a basic configuration. Proceed to the next section,
“Configuring Timing (Clock) Signals.”
Configuring Timing (Clock) Signals
All PA-8T-V.35 interfaces support both DTE and DCE mode, depending on the mode of the interface
cable attached to the port. To use a port as a DTE interface, you need only connect a DTE compact serial
cable to the port. When the system detects the DTE mode cable, it automatically uses the external timing
signal. To use a port in DCE mode, you must connect a DCE interface cable and set the clock speed with
the clock rate configuration command. You must also set the clock rate to perform a loopback test. This
section describes how to set the clock rate on a DCE port and, if necessary, how to invert the clock to
correct a phase shift between the data and clock signals. Table 5-4 on page 5-10 summarizes some of the
commands used to configure the clock rate. See the specific sections that follow for further details.

interface:
“Inverting the Clock Signal”
Router(config)# interface serial 3/0
Router(config-if)# invert-txc
Setting the Clock Rate
The default operation on a PA-8T-V.35 DCE interface is for the DCE device to generate its own clock
signal (TxC) and send it to the remote DTE. The remote DTE device returns the clock signal to the DCE
(PA-8T-V.35). Set the clock rate of an interface using the clock rate subcommand, which specifies the
clock rate as a bits-per-second value. This subcommand functions in the same way on all supported
platforms.
Before you can assign a clock rate, you must use the interface serial command (followed by the
interface address of the interface) to select the interface to which you want to assign the clock rate value.
In the following example, the clock rate is specified as 72 kbps:
Router(config-if)# clock rate 72000
The preceding command example applies to all systems in which the PA-8T-V.35 is supported. Use the
no clock rate command to remove the clock rate.
Following are the standard clock rates:
1200, 2400, 4800, 9600, 19200 38400, 56000, 64000,
72000, 125000 148000, 250000, 500000, 800000, 1000000,
1300000, 2000000, 4000000, 8000000
When you have finished, press Ctrl-Z—hold down the Control key while you press Z—or enter end or
exit to exit configuration mode and return to the EXEC command interpreter prompt. Then write the new
configuration to NVRAM using the copy running-config startup-config command.
Note
Cisco IOS Release 11.2(7a)P or later or 11.1(10)CA or later supports nonstandard clock rates (any value
from 1200 to 8000000) on PA-8T-V.35 interfaces installed in Cisco 7204 and Cisco 7206 routers, and
Cisco 7000 series or Cisco 7500 series routers with a VIP.
Cisco IOS Release 11.1(19)CC1 or later or 11.3(4)AA or later supports nonstandard clock rates on
PA-8T-V.35 interfaces installed in Cisco 7202 routers.
Cisco IOS Release 12.0(3)T or later or 12.0(2)XE or later supports nonstandard clock rates on
PA-8T-V.35 interfaces installed in Cisco 7204VXR and Cisco 7206VXR routers.

Configuring the Interface
Cisco IOS Release 12.0(3)T or later or Cisco IOS Release 11.3(7)NA or later supports nonstandard clock
rates on PA-8T-V.35 interfaces installed in Cisco uBR7200 series routers.
Nonstandard clock rates are rounded (if necessary) to the nearest clock rate that the hardware can
support.
Set a nonstandard clock rate for an interface using the clock rate subcommand. Before you can assign
a nonstandard clock rate, you must use the interface serial command (followed by the interface address
of the interface) to select the interface to which you want to assign the nonstandard clock rate value.
In the following example, a nonstandard clock rate of 1234567 bps is specified:
Router(config-if)# clock rate 1234567
The preceding command example applies to all systems in which the PA-8T-V.35 is supported. Use the
no clock rate command to remove the clock rate.
When you have finished, press Ctrl-Z—hold down the Control key while you press Z—or enter end or
exit to exit configuration mode and return to the EXEC command interpreter prompt. Then write the new
configuration to NVRAM using the copy running-config startup-config command.
The following example shows how to use the show running-config command to determine the exact
clock rate to which the nonstandard clock rate was rounded:
Router# show running-config
Building configuration...
...
!
interface Serial1/0 (interface Serial3/1/0 on a VIP or FlexWAN module)
no ip address
clockrate 1151526
!
...
In the preceding example, only the relevant output from the show running-config command is shown;
other information is omitted.
Inverting the Clock Signal
Systems that use long cables or cables that are not transmitting the TxC (clock) signal might experience
high error rates when operating at the higher transmission speeds. If a PA-8T-V.35 DCE port is reporting
a high number of error packets, a phase shift might be the problem. Inverting the clock might correct this
phase shift.
When the PA-8T-V.35 interface is a DTE, the invert-txc command inverts the TxC signal the interface
receives from the remote DCE. When the PA-8T-V.35 interface is a DCE, this command inverts the clock
signal to the remote DTE port. Use the no invert-txc command to change the clock signal back to its
original phase.
Inverting the Data Signal
If the interface on the PA-8T-V.35 is used to drive a dedicated T1 line that does not have B8ZS encoding
(a method to avoid 15 zeros), you must invert the data stream (both TXD and RXD) either in the
connecting CSU or DSU or the interface. To invert the data stream coming out of the PA-8T-V.35, use
the invert data command. By inverting the High-Level Data Link Control (HDLC) data stream, the
HDLC zero insertion algorithm becomes a ones insertion algorithm that satisfies the T1 requirements.

Invert data only on the PA-8T-V.35 interface or on the CSU/DSU; inverting both cancels out both data
inversions.

no nrzi-encoding
The example disables NRZI encoding on a serial “Configuring NRZI Format”
interface:
Router(config)# interface serial 3/0
Router(config-if)# no nrzi-encoding
1. Mark is an optional argument. When mark is used, it means there is no signal transition; there is data (a mark) at the beginning of a bit interval. When
mark is not used, it means there is a signal transition; there is no data (a space) at the beginning of a bit interval.
All PA-8T-V.35 interfaces support non return-to-zero (NRZ) and non return-to-zero inverted (NRZI)
formats. Both formats use two different voltage levels for transmission. NRZ signals maintain constant
voltage levels with no signal transitions (no return to a zero voltage level) during a bit interval and are
decoded using absolute values (0 and 1). NRZI uses the same constant signal levels but interprets the
absence of data (a space) at the beginning of a bit interval as a signal transition and the presence of data
(a mark) as no transition. NRZI uses relational encoding to decode signals rather than determining
absolute values.
NRZ format, the factory default on all interfaces, is more common. NRZI format, which is configured
with a software command, is commonly used with EIA/TIA-V.35 connections in IBM environments.
Enable NRZI encoding on any interface using the nrzi-encoding [mark] command, where no argument
after the command is interpreted as a signal transition, and mark is interpreted as no signal transition.
This command functions in the same way on all supported platforms. Before you can enable NRZI
encoding, you must use the interface serial command (followed by the interface address of the interface)
to select the interface on which you want to enable NRZI encoding.
In the example that follows, NRZI encoding with a signal transition—no argument—is specified:
Router(config-if)# nrzi-encoding
In the example that follows, NRZI encoding with no signal transition—with argument—is specified:
Router(config-if)# nrzi-encoding mark

The example enables 32-bit CRC on a serial
interface:

Router(config)# interface serial 3/0
Router(config-if)# crc 32

16-bit CRC.
no crc size
The example disables 32-bit CRC on a serial
interface and returns to the default 16-bit
CRC:
“Configuring Cyclic Redundancy
Checks”
Router(config)# interface serial 3/0
Router(config-if)# no crc 32
CRC is an error-checking technique that uses a calculated numeric value to detect errors in transmitted
data. All interfaces use a 16-bit CRC (CRC-CITT) by default but also support a 32-bit CRC. The sender
of a data frame calculates the frame check sequence (FCS). Before it sends a frame, the sender appends
the FCS value to the message. The receiver recalculates the FCS and compares its calculation to the FCS
from the sender. If there is a difference between the two calculations, the receiver assumes that a
transmission error occurred and sends a request to the sender to resend the frame.
Enable 32-bit CRC using the crc 32 command. Before you can enable 32-bit CRC, you must use the
interface serial command (followed by the interface address of the interface) to select the interface on
which you want to enable 32-bit CRC. This command functions in the same way on all supported
platforms.
In the example that follows, 32-bit CRC is specified:
Router(config-if)# crc 32
The preceding command example applies to all systems in which the PA-8T-V.35 is supported. Use the
no crc 32 command to disable CRC-32 and return the interface to the default CRC-16 (CRC-CITT)
setting.
When you have finished, press Ctrl-Z—hold down the Control key while you press Z—or enter end or
exit to exit configuration mode and return to the EXEC command interpreter prompt. Then write the new
configuration to NVRAM using the copy running-config startup-config command.

For command descriptions, refer to the Configuration Fundamentals Configuration Guide publication.
For more information, see the “Obtaining Documentation” section on page vi and the “Obtaining
Technical Assistance” section on page vii.
Note
If you are configuring a PA-8T-V.35 on a Cisco 7200 series router and you want to configure the interface
for half-duplex or Binary Synchronous Communication Protocol (Bisync) operation, proceed to the next
section “Configuring Half-Duplex and Binary Synchronous Communications”; otherwise, proceed to the
“Checking the Configuration” section on page 5-17.
Configuring Half-Duplex and Binary Synchronous
Communications
This section explains how to configure PA-8T-V.35 interfaces for half-duplex and Bisync operation in
Cisco 7100 series and Cisco 7200 series routers.
Note
Cisco IOS Release 11.2(7a)P or later supports half-duplex and Bisync operation on PA-8T-V.35
interfaces installed in Cisco 7204 and Cisco 7206 routers.
Cisco IOS Release 11.1(19)CC1 or later or 11.3(4)AA or later supports half-duplex and Bisync
operation on PA-8T-V.35 interfaces installed in Cisco 7202 routers.
Cisco IOS Release 12.0(3)T or later or 12.0(2)XE or later supports half-duplex and Bisync operation on
PA-8T-V.35 interfaces installed in Cisco 7204VXR and Cisco 7206VXR routers.
The Catalyst RSM/VIP2, Catalyst 6000 family FlexWAN module, Cisco uBR7200 series routers, and
VIP do not support half-duplex and Bisync operation on PA-8T-V.35 port adapters.
Use the half-duplex command to configure PA-8T-V.35 interfaces for half-duplex mode; full-duplex
mode is the default for low-speed serial interfaces. Serial DCE interfaces in half-duplex mode can be
configured for controlled-carrier mode or constant-carrier mode; constant-carrier mode is the default.
Controlled-carrier mode sets the PA-8T-V.35 interface to deactivate data carrier detect (DCD) until a
transmission is sent to the interface. After a transmission is received, DCD is activated and the interface
waits a user-configured amount of time and then transmits the data. After the transmission, the interface
waits a user-configured amount of time and then deactivates DCD. Constant-carrier mode activates DCD
at all times.
Use the half-duplex controlled-carrier command to configure a PA-8T-V.35 interface for
controlled-carrier mode. Use the no half-duplex controlled-carrier command to return the interface to
constant-carrier mode.
Follow these steps to configure controlled-carrier mode on a PA-8T-V.35 interface:
Step 1
At the privileged-level prompt, enter configuration mode and specify that the console terminal is the
source of the configuration subcommands, as follows:
Router# configure terminal
Enter configuration commands, one per line. End with Crtl-Z.
Router(config)#

OL-3563-03
5-15
Chapter 5
Configuring the PA-8T-V.35 Interfaces
Configuring Half-Duplex and Binary Synchronous Communications
Step 2
Specify the interface to configure for controlled-carrier mode using the interface serial subcommand
(followed by the interface address of the interface) and then enter the half-duplex controlled-carrier
subcommand.
The following example is for the first interface of the port adapter in slot 1:
Router(config)# interface serial 1/0
Router(config-if)# half-duplex controlled-carrier
Step 3
Specify the length of the timer delay the interface uses when it is configured for controlled-carrier mode
by using the following command:
half-duplex timer {cts-delay value | cts-drop-timeout value | dcd-drop-delay value |
dcd-txstart-delay value | rts-drop-delay value | rts-timeout value | transmit-delay value}
where value is the length of the timer delay in milliseconds.
The following example specifies a Data Carrier Detect (DCD) drop delay of 100 milliseconds on the first
interface of a port adapter in port adapter slot 1:
Router(config)# interface serial 1/0
Router(config-if)# half-duplex timer dcd-drop-delay 100 ms
Table 5-7 lists the default delay settings and the value argument for each timer you can use with the
half-duplex timer command.

Using the ping Command to Verify Network Connectivity
Using the ping command, you can verify that an interface port is functioning properly. This section
provides brief descriptions of this command. Refer to the publications listed in the “Related
Documentation” section on page iv for detailed command descriptions and examples.
The ping command sends echo request packets out to a remote device at an IP address that you specify.
After sending an echo request, the command waits a specified time for the remote device to reply. Each
echo reply is displayed as an exclamation point (!) on the console terminal; each request that is not
returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!)
indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate that
the connection failed.
Following is an example of a successful ping command to a remote server with the address 10.0.0.10:
Router# ping 10.0.0.10 <Return>
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms
Router#
If the connection fails, verify that you have the correct IP address for the destination and that the device
is active (powered on), and repeat the ping command.
Proceed to the next section, “Using loopback Commands,” to finish checking network connectivity.
Using loopback Commands
The loopback test allows you to detect and isolate equipment malfunctions by testing the connection
between the PA-8T-V.35 interface and a remote device such as a modem or a CSU or DSU. The loopback
subcommand places an interface in loopback mode, which enables test packets that are generated from
the ping command to loop through a remote device or interface cable. If the packets complete the loop,
the connection is good. If not, you can isolate a fault to the remote device or interface cable in the path
of the loopback test.
PA-8T-V.35 Synchronous Serial Port Adapter Installation and Configuration
OL-3563-03
5-29
Chapter 5
Configuring the PA-8T-V.35 Interfaces
Checking the Configuration
Note
You must configure a clock rate on the port before performing a loopback test. However, if no cable is
attached to the port, the port is administratively up, and the port is in loopback mode. You do not have
to configure a clock rate on the port before performing a loopback test.
Depending on the mode of the port, entering the loopback command checks the following path:
•
When no interface cable is attached to the PA-8T-V.35 interface, or if a DCE cable is attached to a
port that is configured as line protocol up, the loopback command tests the path between the
network processing engine and the interface port only (without leaving the network processing
engine and port adapter).
•
When a DTE cable is attached to the port, the loopback command tests the path between the network
processing engine and the near (network processing engine) side of the DSU or modem to test the
PA-8T-V.35 interface and interface cable.
